Photoreceptor UVR8-mediated ultraviolet-B signaling inhibits nicotine biosynthesis in Nicotiana benthamiana

Key Points

• The research aims to explore how ultraviolet-B affects nicotine production in Nicotiana benthamiana through UVR8 signaling.
• Exposed Nicotiana benthamiana to ultraviolet-B light
• Monitored nicotine levels post-exposure
• Analyzed the role of UVR8 receptor in signaling pathways
• Nicotine accumulation decreased significantly after ultraviolet-B exposure
• UVR8 was confirmed to mediate the inhibition of nicotine biosynthesis
